計算機規定
A scientific or graphical calculator that meets JCQ regulations may be used (some GCSE Mathematics and Science papers are non-calculator). Graphical calculators must be set to exam mode; you must clear any stored programs, notes or data before the exam, and the calculator must not be able to retrieve stored text or formulae.
AO1: AO1: Demonstrate knowledge and understanding of scientific ideas, processes, techniques and procedures (32%)
AO2: AO2: Apply knowledge and understanding of scientific ideas, processes, techniques and procedures (42%)
AO3: AO3: Analyse, interpret and evaluate scientific information, ideas and evidence (26%)
根據歷屆試題與評分準則整理（2022–2024）。
計算機程式
Graph: zeros, intersections & turning points
Graphical calculator / GDC (exam mode)
用途: Plot a function to read its roots (zeros), points of intersection, and maxima/minima.
使用時機: Checking solutions, sketching, or solving where an analytic method is hard.
步驟
Graph the function(s) and use the built-in zero, intersect and maximum/minimum tools.
考試提示: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
Numerical equation solver
Graphical calculator / GDC (exam mode)
用途: Solve an equation or find a variable numerically when an algebraic route is long or implicit.
使用時機: Iterative or implicit equations, or to confirm an algebraic solution.
步驟
Use the equation/zero solver, entering the equation and a sensible starting estimate.
考試提示: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
Numerical integration & differentiation
Graphical calculator / GDC (exam mode)
用途: Evaluate a definite integral \(\int_a^b f(x)\,dx\) or a gradient \(f'(x)\) at a point.
使用時機: Checking calculus answers, or where only a numerical value is needed.
步驟
Use the GDC's numeric integral / derivative function with the limits or the point.
考試提示: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
Statistics & probability distributions
Graphical calculator / GDC (exam mode)
用途: 1-var/2-var statistics, linear regression, and cumulative binomial / normal / Poisson probabilities without tables.
使用時機: Statistics questions and hypothesis tests.
步驟
Enter data in the statistics editor, or use the distribution menu (binomial cdf, normal cdf, …).
考試提示: Allowed under JCQ rules, but you must still show your method — an unsupported calculator answer earns no method marks. Clear all stored programs, notes and data (graphical calculators in exam mode) before the exam.
常見錯誤
1high涉及分數: 2Respiration
Forgetting to write calculated answers in standard form or to the correct number of significant figures as instructed in math-heavy prompts.
如何避免: Underline instructions regarding decimal places, significant figures, or standard form in the question stem, and verify your final value matches.
2medium涉及分數: 1Energy and ecosystems
Conflating similar terms such as 'colorimeter' (for color absorption/chromatography) and 'calorimeter' (for dry biomass energy estimations).
如何避免: Use 'colorimeter' for light absorption assays and 'calorimeter' strictly for dry biomass combustion experiments.
3high涉及分數: 2Investigating diversity
Confusing standard deviation overlap principles, failing to state explicitly whether overlaps indicate a significant difference or not.
如何避免: Explicitly write: 'The standard deviations overlap, indicating there is no significant difference between the means, and the difference is likely due to chance' (or vice versa).
4medium涉及分數: 1Homeostasis is the maintenance of a stable internal environment
Failing to state 'many' when describing structural adaptations of the proximal convoluted tubule (e.g. 'many mitochondria', 'many carrier proteins').
如何避免: Always use quantitative descriptors like 'many' or 'numerous' when describing adaptive organelles/proteins in active transport cells.
5medium涉及分數: 1Homeostasis is the maintenance of a stable internal environment
Confusing ADH receptor target locations by calling them simply 'collecting duct' or 'distal convoluted tubule' without specifying both or using unauthorized abbreviations like DCT.
如何避免: State 'collecting duct and distal convoluted tubule' in full; avoid abbreviated terms like 'DCT' which are rejected by examiners.
6high涉及分數: 2Genetic diversity and adaptation
Believing that antibiotics themselves induce mutations for resistance in bacterial populations, rather than acting as a selection pressure.
如何避免: State clearly that mutations arise spontaneously and randomly before antibiotic exposure, and that antibiotics act as a selection pressure.
7high涉及分數: 1Homeostasis is the maintenance of a stable internal environment
Assuming that Type II diabetes is characterized by an absence of insulin production, rather than glycoprotein/receptor insensitivity on target cells.
如何避免: Define Type II diabetes as receptor/glycoprotein insensitivity or resistance to insulin, while Type I represents a lack of insulin production.
8medium涉及分數: 1Skeletal muscles are stimulated to contract by nerves and act as effectors
Stating that the A-band contracts or changes length during the sliding filament theory sequence.
如何避免: Remember that the A-band (myosin length) remains constant; only the H-zone and I-band shorten during sarcomere contraction.
9high涉及分數: 1Transport across cell membranes
Describing 'it' (without naming the specific protein/molecule) in active transport or facilitated diffusion responses.
如何避免: Never use the word 'it' to open descriptions of membrane transport; explicitly write 'the carrier protein' or 'the sodium ion'.
10high涉及分數: 5Using genome projects
Losing synthesis marks in Paper 3 Section B by not linking at least four clear specification references back to the main essay theme.
如何避免: Weave at least four distinct, detailed areas of the specification into your essay, explicitly linking each back to the main essay title.
